The excellent monograph of the Rev. L. Jenyns has been impli-

II. — On the Botany of Erris, County Mayo, and a notice of several 

 additions to the Flora Hibemica. By Charles C. Babington, 

 M. A., F. L. S., &c. 



As the western part of Ireland is not well known to English 

 naturalists, a short account of my botanical observations, made dur- 

 ing a tour in the counties of Mayo and Galway, but more particu- 

 larly the former, may perhaps be acceptable. Had this district been 

 even moderately known, I should not have presumed to introduce 

 so very imperfect a sketch of its native flora, but when I find that it 

 is scarcely noticed in Mr Mackay's Flora Hibernica, I cannot avoid 

 thinking that even these cursory observations may be interesting to 

 British botanists. 



It was about the middle of the month of July 1836 when I arriv- 

 ed at Westport, a small town at the head of Clew Bay, county of 

 Mayo, and determined upon visiting the wild district of Erris. But, 

 during a morning walk, previously to starting for that country, I 

 noticed the following plants, most of them, indeed, very common, 

 yet considered worthy of notice, as showing one of the most wester- 

 ly points of their range. It may perhaps be as well to add, that 

 this is the nearest land to America, although this is not the most 

 westerly part of Ireland. 



On the cultivated land the following plants occurred : Scrophu- 

 laria nodosa, Sonchus oleraceus, S. asper, Circaea lutetiana, Veronica 

 agrestis, V. polita. 



In a bog upon the north side of the harbour, and which is pro- 

 bably sometimes overflowed by the tide : Plantago maritima, Tri- 

 glochin maritimum, Linum catharticum, Glaux maritima, Spergula 

 nodosa, Samolus valerandi, Rumex hydrolapathum, Anagallis te- 

 nella, Carduus pratensis, Ranunculus hederaceus, Hypericum hu- 

 mifusum, Phalaris arunclinacea. 



I also noticed, in the same bog, a species of Rumex differing very
